BOS COSTA against its type
Built in 2007, it is 5 years older than the median bulk carrier on this register, which was built in 2012 (6,882 vessels with a known build year). At 17,663 gross tonnage it is smaller than 94% of the other 6,571 bulk carriers with a recorded tonnage. It is one of 13 bulk carriers here under the Saint Vincent and the Grenadines flag, 0.2% of the 8,138 on the register. Its MRV returns name it UNI AUC ONE for 2019–2020 and BOS COSTA for 2024–2025. The reported port of registry changed: HONG KONG (2019–2020), then Kingstown (2024–2025).
Its 1,305 t of CO₂ for 2025 is 60% below the median of 3,238 t among the 3,732 bulk carriers on this register that reported for 2025. Per nautical mile it emitted 179.0 kg CO₂, 31% below the type median of 260.7 kg. It logged 825 hours at sea against a median of 1,199 hours for its type that year. 1.5% of its 2025 emissions were at berth; the median for bulk carriers was 3.7%. Across 4 years with reported emissions, the highest was 2020 (2,818 t) and the lowest 2019 (1,080 t). Its efficiency percentile within the type went from 63 in 2020 to 85 in 2025 (lower is more efficient). Of the 2 comparable vessels listed below with a 2025 return, 0 reported a lower CO₂ per nautical mile than this vessel.

Efficiency against its own type2025
Position 2,764 of 3,241 qualifying bulk carriers by EEOI, at the 85th percentile. The dashed line is the type median, 7.6; this vessel reported 11.4.
EEOI divides emissions by transport work, which for this vessel and year was 114,213,473 tonne-miles over 7,295 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 20.8% higher than in 2019, for EU/EEA voyages only. No return is recorded for 2021, 2022, 2023, so the series has gaps.
From 2024 to 2025, emissions fell 40.3% while distance sailed fell 30.5%and CO₂ per nautical mile fell 14.2%.That points mainly to how much the vessel sailed, rather than the other.
